Title: Memory device having memory cells with magnetic tunnel junction and tunnel junction in series
Inventor: TRAN LUNG T
IPC: H01L27/10
Filed: 2002-08-29
Granted: 2003-12-21
Abstract: A memory device (10) includes dual tunnel junction memory cells (130, 230, 330) having a magnetic tunnel junction (134, 234, 334) in series with a tunnel junction (134, 234, 334). The magnetic tunnel junction (134, 234, 334) can be changed from a first resistance state to a second resistance state during a write operation. The magnetic tunnel junction (134, 234, 334) can have a differing resistance-voltage characteristic than the tunnel junction (134, 234, 334), and the differing resistance-voltage characteristics allow the magnetic tunnel junction (134, 234, 334) to be blown without blowing the tunnel junction (134, 234, 334) during a write operation. The change in resistance state of the magnetic tunnel junction (134, 234, 334) changes the resistance of the selected memory cell (130, 230, 330), which is detectable during a read operation.

Abstract: Nitrogen is fed into a sealed container (18) to expel oxygen (step 1) and, in such a state, the inside temperature of the container (18) is incrementally raised step by a heater built into the container (18). In sequential steps 2 through 5, water content, chlorine, and high-molecular gases are extracted. Reusable carbon and metal remain in the container (18) in step 6, or when left standing for a prescribed time or more. Gases extracted in steps 2 to 5 can be liquefied for recycling. No carbon dioxide or dioxins are produced because heating is performed in an oxygen-free atmosphere. A furnace is not required because the heater is installed in the container (18), and treatment efficiency is high. A space-saving, energy-efficient, and low-cost treatment system, by which carbon (e.g., inert carbon), metals, and the like can be recovered in a reusable state without producing carbon dioxide or dioxins, is obtained.
